Nemesia plant named ‘Penmys’

ABSTRACT

A new and distinct cultivar of Nemesia plant named ‘Penmys’ that is characterized by a profuse display of dark violet-blue flowers that are uniform, and a more compact form than others in this color range. In combination these characteristics set ‘Penmys’ apart from all other existing varieties of Nemesia known to the inventor.

CROSS-REFERENCES TO RELATED APPLICATIONS

This application is related to another application entitled NemesiaPlant Named ‘Pensug’, having the same inventor as the present invention.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Nemesia,that will be referred to hereinafter by the cultivar name ‘Penmys’. Thenew Nemesia was selected in Netherwent, Caldicot, South Wales on May 1,1998 by the inventor. The parents are of hybrid origin and have notthemselves been released. The first crosses were made in 1997 withplants selected by the inventor from a long term Nemesia breedingprogram.

The breeding program involved cross-pollination of Nemesia hybrids fromwhich seedling selection was based on the production of a dark blueflowering Nemesia, with numerous flowers, uniform flowers, and a compacthabit.

The combined characteristics of the new invention ‘Penmys’ are unique.‘Penmys’ is distinguished from other existing Nemesias by a compacthabit, uniform flowers, and abundant flowers of a dark violet-bluecolor. The closest comparison cultivar is ‘Woodcote’ (unpatented), whichis grown in the United Kingdom. ‘Penmys’ is distinguishable from‘Woodcote’ (unpatented) by its greater abundance of flowers and itslarger dimensions, ‘Woodcote’ (unpatented) being only 15 cm. tall whenin full flower.

The new cultivar was first asexually propagated by the inventor on May1, 1998 in Netherwent, Caldicot, South Wales, using terminal cuttings.‘Penmys’ has been found to be true to type after many cycles ofvegetative cuttings from 1998 to the present.

SUMMARY OF THE INVENTION

The following traits have been repeatedly observed and represent thedistinguishing characteristics of the new invention. ‘Penmys’ isfree-flowering, with dark violet-blue, uniform flowers and a morecompact habit than other Nemesias in this color range. In combinationthese traits distinguish ‘Penmys’ from all other existing varieties ofNemesia known to the inventor.

BRIEF DESCRIPTION OF THE DRAWINGS

The accompanying color photographs illustrate the overall appearance ofthe new cultivar.

Sheet 1 illustrates the entire plant and habit.

Sheet 2 is a close-up view of the flowers.

Sheet 3 illustrates a stem with leaves and flowers. All photographs aretaken of plants grown in two-gallon containers. The prints were madeusing conventional photographic techniques and although colors mayappear different from actual colors due to light reflectance, they areas accurate as possible by conventional photography.

BOTANICAL DESCRIPTION OF THE PLANT

The following is a detailed description of the Nemesia cultivar named‘Penmys’. Data was collected in Arroyo Grande, Calif. from 9-month-oldplants grown in two-gallon containers. Phenotypic differences may beobserved with variations in environmental, climatic, and culturalconditions. The color determinations are in accordance with The RoyalHorticultural Society Colour Chart except where general color terms ofordinary dictionary significance are used. The growing requirements aresimilar to other Nemesias and ‘Penmys’ is resistant to common pests anddiseases.
